to which it appertains to make and use the same.

My invention relates to improvements in hoisting devices and more particularly to those adapted for use in raising motor ve hicles and the like.

The object, of the invention is to provide "a comparatively simple device of this character possessing a number of novel and advantageous features, and so constructed as to render it readily adjustable for application to vehicles of different sizes.

With this and other objects in view, the invention resides in certain novel features of construction and combination hereinafter described and claimed and shown in the drawings wherein;

Figure 1 is a side elevation of av device constructed in accordance with my invention showing the same in lowered position; Fig. 2 is a central vertical longitudinal section showing the positionlng of parts when a vehicle is supported on the hoist; Fig. 3

is a top plan view; Fig. 4 is a vertical transverse section as seen along the plane of the line 44 of Fig. 1; and Fig. 5 is a detail vertical longitudinal section showing more particularly the construction of one of the axle rests.

In these drawings constituting a part of the present application, the numerals 1 designate a pair of parallel horizontal tracks,

here shown as formed of channel iron with the channels thereof located on the inner opposed faces of the tracks. Hingedly connected to the opposite ends of the tracks 1, are the arms 3 of a pair of U-shaped end frames 4 whose cross bars 5 are equipped with casters 6 and with bearings 7 which are pivoted to their'intermediate portions, these hearings receiving a longitudinal shaft 8 Whose opposite ends are externally threaded and equipped with cranked nuts 9. By this construction, rotation of the nuts 9 in the proper direction will move the end frames 4 from the position seen in Fig. 1 to that seen in Fig. 2, thus ra1s1ng the tracks 1. It

may here be explained that the hinges 2 are I of such construction as to permit these end frames to swing outwardly to the necessary extent, but will not permit them to swing inwardly to an extent greater than to position them at right angles to the tracks 1 and, if desired, the worm shaft 8 may be provided with stops 10 adapted to abut the bearings 7 to positively prevent the end frames from moving to an extentgreat enough to injure the hinges. Furthermore, these stops 10 assist in imparting rigidity to the structure when in active position as seen in Fig. 2.

Extending transversely of the tracks 1 and having their opposite ends slidably mounted in theichannels thereof, is a pair of carriages each composed of two parallel rods 20, one" pair of such rods being disposed at each end of the device. As most clearly seen in Figs. 2 and 4, these rods support a plurality of bearings 21 which are mounted thereon to slide longitudinally thereof, said bearings being equipped with upwardly converging bars 22 which are received by the hollow legs 23 of a number of inverted V-shaped axle rests 24, these legs and the bars being provided with a series of spaced apertures through which pins or the like 25 are adapted to be passed. The rests 24 are further equipped with seats 26 at their upper ends, these seats being so shaped as to readily receive the axles of a vehicle.

With the parts constructed as above described, the entiredevice may be positioned beneath the vehicle to be raised, and the two pairs of rods 20 (constituting the carriages) may be adjusted longitudinally upon the tracks 1 to position the axle rests 24 under the front and rear axles of said vehicle If obstructions are now encountered, these rests 24 may be adjusted transversely upon the rods 20, and may also be adjusted vertically if necessary. The cranked nuts 9 are now rotated to draw the two end frames 4 inwardly toward each other, thereby raising the two tracks, the two carriages thereon, and the entire vehicle. A

From the foregoing description taken in connection with the accompanying drawings, it will be seen that a very simple construction has been provided for carrying out the object of the invention, yet that a device constructed in this manner will possess a number of advantageous features and will be very efiicient in operation.

The invention has been described with considerable detail, and in the drawings, a number of mechanical expedients have been provided for reducing such invention to an operative structure, but it will be readily understood that I need not be limited to such mechanical details otherwise than as set forthxin the appended claims.

I claim 1. A device of the class described comprising a pair of parallel wheel supported tracks having channels on their inner opposed faces, an axle rest rising above one end of said tracks, a pair of parallel transverse rods having their ends mounted to slide in said channels and a pair of axle rests rising from said rods and adjustable longitudinally thereon.

2 "A device of the class described comprising a pair of parallel tracks having channels on their inner opposed faces, an axle rest rising above one end of said tracks, a pair of parallel transverse rods having their ends mounted to slide in said channels, two pairs of independent bearings mounted on the ends of said rods to slide longitudinally thereon, upwardly converging bars rising from said bearings, and inverted V-shaped axlerests secured to said bars for vertical adjustment.

3. A device of the class described comprising a pair of parallel tracks having channels on their inner opposed faces, an axle rest rising above one end of said tracks, a pair of parallel transverse rods having their ends mounted to slide in said channels, two pairs of independent bearings mounted on the ends of said rods to slide longitudinally thereon, upwardly converging bars rising from said bearings, and inverted V-shaped axle rests-having hollow legs adjustably receiving said bars.

l. A device of the class described comprising a pair of parallel longitudinal wheel" supported tracks formed of channel iron nesses.
